Empire of Ashes

*Featured once upon a time*
A kingdom crumbles.
A country falls.
A civilisation is reduced to bones.
Lyra is just one of thousands of captives in a war which has raged for generations. Her home and birthplace- Cambria, has been conquered by an ambitious king. Enslaved and shackled, she is marched off to serve Temris, a ruthless Warlord in the pay of the enemy. But Temris is not all he seems to be and while with him, Lyra finds a chance in a million of overthrowing the tyrant who destroyed her whole life.

I like her clever strategy but doesnt "carcass" mean dead body? Can it refer to an unconcius person? You could say something like the "prone form of the first guard" or something like that. I defer to your judgment.
